SPECIFICATION forming part of Letterslatent No. 743,696, dated November 10,1903.

` Ap'lnmionlnea June so, 1902. sans No. 113,322. on man.)

To @ZZ whom, it may concern) Be itknown thatI, ALBERT S. DIXON, a citizen of the United States, residing at Los Angeles, in the county ot' Los Angeles and State of California, havel invented new` and useful Atomizer, of which the following is a specication. i Y

This invention is designed for breaking up and atomizing liquids under the pressure of an expansive fluid for spraying or distributing the liquid.

A special object of the invention is to provide means whereby thick hydrocarbons may be reduced to vapor and supplied in perfectlyregulated quantities to the tire-box of a furnace, so that the lire may be constantly maintained at any determined volume and force.

In this invention a rotary member is mounted in a chamber which is formed in a body having an inlet arranged to direct a jet ot expansive medium, as steam or air, tangentially against the periphery of said rotaryA member, an outlet through which the said expansive m'edium may escape from the chamber after giving a rotary impulse to said member, and an inlet for the liquid fuel. rotary medium is desirably furnished with projections, which may be formed as teeth or by notches or otherwise.

An object of the invention is to construct and arrange parts so asto avoid wear and to increase the life of the apparatus.

Another object of the invention'is to make provision for feeding to such device thick.

heavy hydrocarbon oils without anyliability of clogging. e

The invention may be applied in various forms, and I do not limit myself to any specitic construction, the purpose in View being to produce a construction by means ot which.

II of Fig. I. Fig. II'I is a view of the end ofthe the rotary member l. `regulating the inow and for readily keeping said inlet open and free the inlet fr' may -be located opposite the end of. the rotary vmember l and axially relative to such rotary The Y nozzle shown in Fig. II. Fig. IV is a View of another form of the invention. broken elevation of the same, partly in section on line V V of Fig. IV. Figs. VI and VII are end and side views, respectively, of a `torm of the rotary member.

. 1 designates a toothed rotary member arrangedto rotatein a chamber 2, formed in a body 3, 'which has an inlet 4 for an expansive medium arranged to direct a jet of such medium tangentially against the teeth 5 of said member l below the axisof said member and toward an outlet 6, which is desirably of a considerable diameter compared With that of the inle'ta. Y

'7 is an inlet for the liquid fuel, which inlet communicates against the closed end of For the purpose of member, and said member maybe provided with va projection in the form of a dnger or p in 8,'arranged eccentrically, so that as the .rotary member turns the part 8 will act as a wiper to keep the oil-inlet 7 clear.

This pin or projection may be of any form which may serve the purpose stated.

9 is a spindle on which the rotary member 1 lnay be mounted to rotate freely, a socket l0 in said member being provided for this purpose and desirably extending from the medium may pass almost directly through the chamber 2, rst having acted upon the toothed periphery of the member l. A portion of said expansive medium, however, will be enmeshed between the teeth, andV other portions will be spread out laterally to pass around at the ends of the rotary member, which may be arranged by any suitable means, such as the bead l1 and the spindle 9, to rotate freely in the chamber 2, with a clear space all around the member 1 to allow an intermingling of the expansive medium and the liquid. A further advantage of lo- Fig. V is a eating the lowerl notched periphery of the member-1 in line between the inlet 4 and the outlet 6 is that the expansive force of said medium will tend to support the rotary member in the' chamber, thus lightening said member on its bearing, avoiding wear, and increasing the life of the parts. This arrangement also applies the expansive force to lift the liquid which is admitted at the axis of the rotary member, so that said liquid will not immediately pass to the outlet 6, but will partake of the rotation and will be thrown to the periphery of the chamber by centrifugal force and will be acted upon in said chamber by the rotary member and the expansive.

fluid and will finally issue through the outlet 6 well broken up and intermingled with the expansive Huid.

12 represents a nozzle or discharging appliance, which may be of any requisite form to receive vapor from the outlet 6 and deliver it to the re-box or wherever else the atomized liquid is to be applied.

The inlet7 communicates against the closed end of the rotary breaker and miXer,1, communicating into the chamber 2 in alinement with the axis of said rotary member. The rotation of the member 1 thus serves by ceutrifuga'l action to break up the oil as it is thrown out toward the periphery of the member 1 and to admix therewith steam rising from the tangential inlet 4. To heighten the centrifugal action of the rotary member 1 upon the liquid, the closed or imperforate end or face of said member, which is toward the liquid-inlet 7, maybe notched or corrugated in radial or other lines. q

13 designates a form of corrugation which I deem desirable.

The nozzle-outlet 14 is desirably of large cross-sectional area compared with the crosssectional area. of the inlet 4, so that no great pressure will be produced by the expansive medium inside the chamber 2. The body of the nozzle 12 between the chamber 2 and the nozzle-outlet 14 will be of considerably larger crbss-sectional area than such outlet, so as to form a nebulizing-chamber,between the mixing-chamber 2 and the outlet 14. Desirably the pipe or body of the nozzle 12 will be of such length as to allow the body 3 of the atomizer to be located at a convenient distance from the front of the furnace, so that it will not become overheated.

Itis desirable that means be provided for moving the rotary member' 1 toward the liquid-inlet 7, thus to regulate the amount of liquid which may flow under a given pressure into the chamber 2. For this purpose the spindle 9 may have a screw-threaded portion 15, which screws through a female screw 16 in a portion of the body 3, so that when the spindle is turned in one direction it will advance toward the inlet 7, thus to force the rotary member toward said inlet to limit the flow of oil therethrough.

17 is a handle fastened to an angular portion 18 of the spindle by a screw 19 for turning the spindle. Desirably the body 3 has a circular portion 20, which may be marked with a scale 21, and the arm 17 extends into position -to swing around the periphery of said circular portion.

22 is a set-screw screwed through the arm 17 and against the periphery of the circular portion 20 to tix said arm in any determined position. The purpose of this is to enable the attendant to gradually adj ust the spindle 9 to any depth in the chamber 2, so as to hold the rotary member 1 positively toward the liquid-inlet 7. The scale enables the attendant to determine the arc through which the arm moves. It is not in practice necessary to provide any means for moving the rotary member 1 away from the inlet 7.other than the pressure of the liquid as it enters the chamber 2. It is to be understood that the liquid must bejintroduced into the chamber under a sufficient head, and this may be provided by any of the well-known means for such purpose. The adjustment of the rotary member 1 toward the inlet 7 must be made with reference to the head or pressure of the liquid and the pressure of the expansive medium. Y

It is to be understood that the steam will be applied through a valved pipe 23, the Valve of which is not shown in the drawings, and

that to increase the re an increased amount of steam and oil will be admitted tothe chamber 2. `To increase the amount of oil thus admitted, the handle 17 may be turned to nnscrew the spindle 9 and draw it away from the liquid-inlet', thusallowing a greater quantity of oil to be admitted. At the same time more steam should be turned on. To reduce the tire, the handle 17 will be turned in a reverse direction, thus forcing the spindle 9 and the rotary member 1 toward the inlet 7 to reduce the space through which the oil may enter the chamber.

The body 3 may be formed of two members a and b, fastened together by screws c, and

'the member b may be provided with a screwthreaded hub d, which is provided with the female-screw-threaded portion 16, and the spindle 9 is inserted through said bearing and screwed through the screw-threaded portion 16.

e is a packing-gland on the end of the hub d. The inlet 4 is desirably contracted to form a nozzle to direct a jet forcibly against the be adj usted by the usual valves.

the inlet 7 may be'conical, as shown at 'g in` Fig. IV, so that corresponding movements ofthe arms 17 and the resultant endwise movements of the members 1 in the two forms shown would cause a less variation adjustment of the inletin the case of the form shown in Figs. I and Il than in the form shown in Figs. IV and V.

I make whatIcall right and left hand burners to adapt the appliance to diderentlyarranged furnaces, it being desirable that the inlet and outlet 4 and 12 be at the lower side of the apparatus and that the handle 17 shall always be on the side away from the furnace-door. (Notsbown.) In Figs. I, Il, VL'

and VII what I call-a left-hand burner is shown, and in Figs. IV and V what I term a right-hand burner is shown.

Iu-practical operation of the device as applied for hydrocarbon-furnaces the appropriate quantities of oil andexpansive mediu m, as steam or air, will be supplied through the inlets 7 and 4, respectively, whereupon the impact of the expansive medium upon the rotary member` will drive the same, and the oil will be broken up and carried into the chambered discharge body or pipe 12, where the liquid and expansive medium will become further intermingled and will then issue through the contracted outlet or nozzle-mouth' 1&,which is desirably arranged flatwise in the usual manner of such nozzles. To adjust the fire, the arm 17 may be moved in one or the other direction to increase or decrease the iiow of the oil in the chamber 2, and the amount of expansive medium will likewise (Not shown in the drawings.)

The appliance may be employed for uses other than those herein speciied.

As described, it is seen that the rotary breaker and mixer 1 forms, in effect, a rotary valve between which and the walls about the opening or axial inlet 7 `any dirt, sand, or other impurities contained in the oil are effectually ground up, and that by regulating, as, for instance, by change of position of 'the spindle 9, the distance of the face or side of the rotary breaker and mixer 1 from these Walls any desired inlet of oil is secured.
